Please advise is the below check is correct as as i am trying to avoid the null pointer exception , folks please advise how to overcome from this
if ((Integer.valueOf(subProductTolerancesMap.get(subProduct))!= null) && (Integer.valueOf(subProductTolerancesMap.get(maxSubProduct))!=null) )
{}
It is not correct. If your subProductTolerancesMap is null, you will get a NullPointerException with that code.
Further, if subProductTolerancesMap.get(subProduct) is null or if subProductTolerancesMap.get(maxSubProduct) is null, you will get a NumberFormatException.
